Pretty cool that you can mix and match the 3 different layers, too.
Here are some crappy iPhone pics. The sensor doesn't pick up the colors very well, especially red and yellow.
The blue is just a different "blue". I believe it's the Light Blue. The Ice Blue seems a bit duller, like a matte blue. The second one is actually Yellow. The third is Red (I believe the Bright Red version). The others are pretty obvious I think
